The invention consists in the construction shown. The lower boss 5 of the valve-casing 20 and combination of parts in a gas-pressure is arranged for the attachment of a gas-inlet 7o regulator, as hereinafter more fully described pipe, and the upper boss (3 is for attachment and claimed. of a delivery-pipe. It will be observed that In the annexed drawings, illustrating the these bosses 5 and 6 are in line with each invention, Figure 1 is a vertical section of a other and so located that a straight delivery- 2 5 liquid sealed tubular balaneed-valve gas pipe can be attached without coming in conpressure regulator embodying my improvetact with the regulator-easing.

This parted to the valve 18, the gas inelosed in the I00 tubular valve-extension 19 finding a vent back and forth through the perforations 20 with each movement of the valve. It will thus be seen that the valve is balanced in an effective inai'iner to automatically control or regulate the volume and pressure of gas flowing through the apparatus.

If desired, weights 22 may be placed on the upper end of the stem 17, which projects above the float.

Vhat I claim as my invention is- 1. In a gas-pressure regulator, the combination of a valve-casing having a depending tubular extension and a partition provided with a gas-passage and a valve-seat, a regulator-casing attached to the upper part of said valve-casing in line with said tubular extension, a stationary perforated tube vertically and centrally supported in the regulator-casinand communicating with the valve-casing, a liquid-sealed float inclosed in the regulatorcasing' and having a stem that is passed through said tube, and a tubular liquid-sealed balanced valve attached to the float-stem and inclosed in the tubular extension of the valvecasing, substantially as described.

2. 111 a gas-pressure regulator, the combination of a valve-casing having an inlet and outlet and a horizontal partition provided with a gaspassage and valve-seat, a tubular extension depending from one end of the valve-casing, a regulator-casing above and in line with said extension, a vertical stationary tube supported in the regulatorcasing and communicating with the valve-casing, a hollow liquid-sealed float inclosed in the regulator-casing and having a stem that is passed through and guided in said tube, and a tubular liquid-sealed valve inclosed in the tubular extension of tllOVitlVG-CfLSlllg and having a perforated cup-shaped portion attached to the float-stem, substantially as described.

111 testimony whereof I have affixed my signature in presence of two witnesses.
